Curious if anyone here has done an OpenInverter build with SiC, and whether there are unique constraints on the firmware side that make this difficult (switching frequency, for example).

I may have a source for a pile of lightly used 450A 1200V SiC modules + gate drives.

I think I heard somewhere that SiC is harder to drive than IGBTs (I can't comment on why though sorry). I would assume it works but I think that you might better off using a Ti DSP to take advantage of the fast current loop tech and lower loop times. I know it's more efficient than running open inverter software but I can't say how much more.
